In an article on truth written by theologian R.R. Reno in July 2009, the author observes that reality anchors the intellect rather than the intellect constructing or constituting reality. Our culture has it backwards as it uses the intellect to spawn a fantasy reality where anything goes no matter how bizarre or nonsensical. The result is a culture of death. Truly, the emperor has no clothes.
As Reno observed,
The Church contributes to world by speaking the truth about our humanity, a truth vouchsafed in Christ, a truth that must be spoken in season and out.
The problem is that much of the church has muted its witness, shielding the truth - its' most powerful weapon. It's easy to speak truth when it's in vogue but can be quite costly when it's scorned (precisely when truth is most needed.) When a culture jettisons the anchor to reality, all bets are off. At that point, the church that is embedded in the culture is along for the wild catastrophic ride - unless it stands firmly and inflexibly (usually at great cost) with truth.
Theologian Garrigou-Lagrange (1877 - 1964) correctly identified relativism as the enemy of truth. The antitode is a firm, inflexible committment to truth ... something that fewer and fewer seem willing to do today. The video above contrasts critical reason with love of truth. Someone that relies soley on critical reason will be stunted in their intellecual health as something more is needed - the love of truth. It is the love of truth that ultimately brings someone to their full potential and firmly cements them into reality. When the church loves the culture more than truth, it becomes little more than entertainment. Without truth, we are doomed to wander in a fantasy fog on the edge of cliff in this fallen world, until finally we fall inevitably and irretrievably to our death.
We must seek to reignite a love of truth.
... for those who are perishing, because they refused to love the truth and so be saved (2 Thess 2:10, ESV)
Rather, speaking the truth in love, we are to grow up in every way into him who is the head, into Christ (Eph 4:15, ESV)
